Abstract: Four forest types, which include mixed coniferous and broad-leaved forests, mixed broad-leaved forests, Mongolian oak forests and larch plantations, were investigated in Wangqing forestry bureau, Jilin Province, an over-logged forest area in Northeastern China. Plant species diversity was studied by Detrended Correspondence Aanalysis(DCA), community intrinsic diversity ordering and variance analysis. Results showed that species diversity index of mixed coniferous and broad-leaved forests was the highest, that of mixed broad-leaved forests and Larix plantations the next, and that of Mongolian oak forests the smallest. The paper put forward silvicultural practice suggestions for maintaining and conserving diversity of these forests.
